(1) Background: Obstetric violence has been highlighted in the political and social agenda of several countries. Efforts have been made to create policies to humanize obstetric care, guarantee the rights of pregnant women and respond to this form of violence. The lack of consensus on the appropriate terminology to name and define the behaviours that constitute obstetric violence, hinders this process. (2) Objective: To analyse the concept of obstetric violence related to assistance to women during labor. (3) Methodology: Scoping review protocol, according to the Joanna Briggs Institute method. The search will be performed on EBSCOhost Research Platform, PubMed, Virtual Health Library and SciVerse Scopus databases. The Open Scientific Repository of Portugal will also be considered. All types of studies, published in the last 10 years, in English, Spanish and Portuguese languages, constitute inclusion criteria. Studies of women experiencing labor, in a hospital setting, that address the dimensions of the concept of obstetric violence will be reviewed. (4) Discussion: The results will serve as a basis for identifying the appropriate terminology of the concept of obstetric violence, in order to direct future research with interest in the problem.

Taking into account the growing increase in the political and social interest in childbirth, it is critical to identify and explore the instruments that allow and enhance its humanization today. The use of vocalization seems to be a powerful and empowering tool for a positive birthing experience when used by women in labour. A scoping review will be developed to map the evidence and knowledge about women’s vocalization in the first and second stages of labour using the Joanna Briggs Institute methodology. The search will be carried out on the Web of Science, EBSCOhost Research Platform (selecting Academic Search Complete, MedicLatina, Cinahl plus with full text, Medline with full text), Willey Online Library, PubMed and Scopus. The National Register of Theses and Dissertations and the Open Scientific Repository of Portugal will also be taken into account. Three reviewers will conduct data analysis, extraction and synthesis independently. The outcomes pretend to be a source for identifying the use of vocalization by women in labour, in order to guide further research on the subject. This study was prospectively registered with the Open Science Framework on the 21 May 2024, with registration number DOI 10.17605/OSF.IO/Z58F4.

Objetivo: Analisar na literatura publicada, entre janeiro de 2007 e fevereiro de 2016, as evi- dências científicas sobre os benefícios da liberdade de movimentos e posições no primeiro estádio do trabalho de parto. Métodos: Revisão da literatura com artigos pesquisados em bases de dados selecionadas, nas plataformas b-On e EBSCOhost, através dos descritores em língua inglesa: first stage of labour/labor, ambulation, upright positions, benefits e midwife/midwives. Resultados: Amostra constituída por 15 estudos, que demonstraram, de forma quase unâ- nime, que a deambulação associada à posição vertical confere um conjunto de efeitos be- néficos, designadamente na progressão do primeiro estádio do trabalho de parto, na dimi- nuição da dor e aumento da satisfação materna, na qualidade das contrações uterinas e na circulação materno-fetal, comparativamente à posição de litotomia dorsal. Conclusões: A mulher deve ter direito de escolha, quanto à liberdade de movimentos e po- sições no decurso do primeiro estádio do trabalho de parto, sendo informada pela enfer- meira que a assiste, sobre os benefícios destas intervenções. Descritores (DeCS): Deambulação precoce; modalidades de posição; trabalho de parto; en- fermeira obstetra. AbstractObjective: To analyse the scientific evidence, in the literature published between january 2007 and february 2016, about the benefits of freedmon of movement and position in the first stage of labor. Method: Review of literature with articles researched in selected databases on plataforms b-On and EBSCOhost, using descriptors: first stage of labour/labor, ambulation, upright positions, benefits and midwife/midwives. Results: Sample with 15 studies that showed, almost unanimously, that the free movement associated with the vertical position provides numerous benefits, especially in the pro- gression of the first stage of labor, reduction of pain and increased maternal satisfaction, in the quality of uterine contractions and maternal-fetal circulation compared to the dor- sal lithotomy position. Conclusion: Woman should have the right of choice as to freedom of movement and po- sition during first stage of labor, being informed about the benefits of this intervention by the nurse midwife who cares for her. Descriptors (MeSH Terms): Walking; posture; labor, obstetric; nurse midwife.
